I have 2 motorhomes. 1 is a 38' Newmar Mountain Aire and then a 19' Roadtrek Versatile. While the Roadtrek is 1/2 the length it has about 1/20th the amount of storage space. Holding tank and water tank are very small compared to the Class A and need changing and filling frequently. For 2 people the Roadtrek would be a little cramped. After being an RVer since 1969 and having 5 MHs TTs, popups and a HiLo I look at the little one and see how they have to build with limitations due to location capability of appliances, tanks and weights. There is a lot more flexibility in the larger RVs for changes to be made.
